What should I do if Face ID isn’t recognizing my face?
If Face ID isn’t recognizing your face, the first step is to ensure that there are no obstructions such as sunglasses, face masks, or any other items that may block your facial features. Keep the front camera area clean and free from dirt or fingerprints, as they can interfere with the sensor. Additionally, check for proper lighting; Face ID might struggle in low light conditions.
If after addressing these issues Face ID still isn’t working, try resetting the Face ID settings. Navigate to Settings > Face ID & Passcode and select “Reset Face ID.” After this, set up Face ID again by following the on-screen instructions.
